Assessment of Genetic Variability in Prolactin Gene and Its Impact on Milk Composition in Bos indicus Cattle

India is homeland and origin place of many elite cattle breeds of the world and possesses around 40 well recognized Bos indicus breeds of cattle (Anonymous, 2013) which holds great promise and potential for milk production in addition to their exemplary adaptability to tropical climate. The effective assessment of genetic variability in genes affecting the physiological pathways of milk composition traits (Agrawal et al., 2018) and incorporation of this genotypic information as fixed factor in estimation of breeding value could significantly improve the selection responses and potential values of the indigenous cattle genetic resources (Mohammed et al., 2015). Newer breeding goals especially on milk composition traits have recently gained importance following International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 6 (2020) Journal homepage: http://www.ijcmas.com
